Problem#1 (Chapter 7 problem 8) [Previous days hometask]
Write a program that prompts the user to enter a character, and on subsequent lines prints its ASCII code in binary, and the number of 1 bits In Its ASCII code.
TYPE A CHARACTER: A
THE ASCII CODE OF A IN BINARY IS 01000001
THE NUMBER OF l BITS IS 2
mov ah, 1 int 21h mov bl, al mov bh, 0 mov cx, 8 mov ah, 2 mov dl, 0Ah int 21h mov dl, 0Dh int 21h start: ROL BL, 1 Jc one zero: mov dl, '0' int 21h jmp end_ one: inc bh mov dl, '1' int 21h end_: loop start mov dl, 0ah int 21h mov dl, 0dh int 21h add bh,'0' mov dl, bh int 21h
Problem#2 (Chapter 8)

Problem#3 (Chapter 7 problem 12)
Write a program that prompts the user to enter two binary numbers of up to 8 digits each, and prints their sum on the next line in binary. If the user enters an illegal character, he or she should be prompted to begin again. Each input ends with a carriage return.
TYPE A BINARY NUMBER, UP TO 8 DIGITS: 11001010
TYPE A BINARY NUMBER, UP TO 8 DIGITS: 10011100
THE BINARY SUM IS 101100110
